Dear sagefriends,

(sorry for my English)

Let us define
   var('t'); q=sin(t)^2 + cos(t)^2
By using simplify(q) we again get
   sin(t)^2 + cos(t)^2

Instead of simplify() we can use full_simplify() and trig_simplify().
But both full_simplify(q) and trig_simplify(q) give an error message.
You must use
   q.full_simplify()
or
  q.trig_simplify()
to get the answer 1.

But this kind of notation as a method is very strange for many people.

Wy not to add the possibility of use full_simplify(q) or similar for
many
other methods?

Perhaps it is too complicate to implement it, I don't know...

Yours,

Juan Luis Varona
